| In recent years, because the country give priority to infrastructure construction increases investment strength, the highway because of the great social benefit and economic benefit to become an investment focus. Huge investment and project quantity need scientific and elaborate management guidance, as throughout the expressway project management through contract management is the priority among priorities.Long-term since, because the highway engineering construction site a long front, the construction unit resident dispersion, traffic inconvenience and other reasons, caused by the owner, supervision unit and construction unit of information transfer between not free, delivery timely, serious impact on the implementation of management behavior. The owners, supervision units on the field of mastery is restricted, thereby constraining the owners, supervision units, construction units between each other to convey information timeliness and accuracy.In order to solve the problem of highway construction contract management for the existing problems, we did the following respects to work:First of all, according to the contract management in highway construction process as well as the importance of contract management definition, analysis of contract management and the contract management informatization in foreign and domestic development situation, identifies the major research content, discussed highway contract management information significance;Secondly, through the study on the characteristics of contract management, contract management and other management of the relationship between, discussed highway contract management business structure, and combined with the contract management system using environment and user groups needs, determine the system uses B/S model architecture;Then, through the analysis of highway contract management demand, type of business and business flow, expressway management system should have the function and performance characteristics, making the highway contract management system design ideas, select the system platform, the research of contract management system database selection, coding standard design, form design, backup and disaster recovery design and other aspects, to solve the design of system security, data exchange and interface structure and a series of problems;Finally, the system construction of the basic principles, the system structure and the logical structure design, proposed based on MVC expansion morphology system design model, and according to the highway contract management business needs of the system function design, shows the highway contract management system key technology and characteristics of.Currently, the system has been running in the Changde to Jishou highway project, proved stable operation, full-featured, reliable performance to achieve the original intended design goals, the unanimous endorsement of the user. |
